The key is probably in getting the plot of Tdiff vs Esum calibrated [Tdiff is time difference between S2-1 and S2-2 signals and Esum is the sum of their energies].&nbsp; The problem is that the TDC signals have not yet been lined up.&nbsp; We also need to understand the features we see in the E vs t plots, including the puzzeling feature that one of the loci has its &quot;blob&quot; of events at a different energy than the others.</p> <p>My feeling is that we should continue to run ast this energy, while continuing to refine the sort to try and confirm we can select out the (a,p) events of interest.</p> <p>Worth thinking as to whether we should take more beam (it is available.</p> <p>&nbsp;</p></td> </tr> </tbody> </table> </p><p> </p> Encoding: HTML   ELCode   plain   Suppress Email notification Attachment 1:
